nagios 监控流量插件check_traffic

一,安装所需软件net-snmp net-snmp-utils net-snmp-libs net-snmp-devel

   yum install net-snmp net-snmp-utils net-snmp-libs net-snmp-devel bc

二,修复snmp配置:

vim /etc/snmp/snmp.conf 修改为:

#       sec.name  source          community

#com2sec notConfigUser  default       public

com2sec notConfigUser  localhost      public

access  notConfigGroup ""     any    noauth  exact  mib2 none none

view mib2   included  .iso.org.dod.internet.mgmt.mib-2 fc

三,启动snmp服务:

service snmpd start

四,设置开启启动:

chkconfig snmpd on

五,上传插件到/usr/local/nagios/libexec (插件在附件中)

六,配置

测试check_traffic 脚本:

cd /usr/local/nagios/libexec

./check_traffic -V 2c -C nagios -H localhost –L命令列出网络接口

然后更改所属 chown nagios:nagios check_traffic.sh
执行如下命令查看网卡 /usr/local/nagios/libexec/check_traffic.sh -V 2c -C nagios -H localhost -L (which: no bc in (/program/system/jdk1.6/bin::/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin) Can not found command bc in you system PATH: /program/system/jdk1.6/bin::/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin, pleas check it *****解决办法 yum install bc )


cd /usr/local/nagios/etc

vim nrpe.cfg #添加

command[check_traffic]=/usr/local/nagios/libexec/check_traffic -V 2c -C public -H localhost -I 2 -w 2200,4000 -c 2500,4500 -K -B

-I 2 指网卡接口(就是你要监控的网卡接口)

修改chown nagios:nagios /var/tmp/check_traffic_localhost_2.hist_dat

重启nrpe 服务

七,配置监控服务器:

cd /usr/local/nagios/etc/objects

编辑vim services.cfg中添加:

define service {
       use services-pnp
       host_name xxx-Server
       service_description check-traffic
       check_period 24x7
       max_check_attempts 4
       normal_check_interval 3
       retry_check_interval 2
       contact_groups sagroup
       notification_interval 10
       notification_period 24x7
       notification_options w,u,c,r
       check_command check_nrpe!check_traffic
}

八,测试
